Specific embodiment
As depicted in figs. 1 and 2, a kind of folding children's barrow, including two symmetrically arranged side stands 1, two collateral
The bottom of frame 1 is provided with front-wheel 152 and rear-wheel 153, and each side stand includes handspike 11, front rod 13, back link 14 and bottom
Bar 15, bottom bar 15 include horizontally disposed main part and front-wheel seat bar 151, the top of front rod 13 bottom end and front-wheel seat bar 151
End is hinged, and top and handspike 11 are hinged.The bottom end of back link 14 and the middle part of bottom bar 15 are hinged, the bottom on top and handspike 11
End is hinged, so that front rod 13, bottom bar 15, back link 14 and handspike 11 constitute foldable four-bar mechanism.
Bottom bar as described above includes horizontal component and the front-wheel seat bar 151 that is vertically arranged, and the two is fixedly connected, front-wheel seat bar
151 bottom is equipped with front-wheel 152, and the rear end of bottom bar 15 is bent downwardly, and is equipped with rear-wheel 153.
As depicted in figs. 1 and 2, it is provided with cross bar and two right-angled intersection bars 19 between two side stands 1, cross bar 21 is set to
Between two handspikes 11, cross bar 22 and cross bar 23 are set between two foundation bars 15, and all cross bars are two-part pole structure,
I.e. cross bar is formed by two sections be mutually rotatablely connected, naturally it is also possible to is multisection type pole structure, such as three sections, four sections, only be needed
Meet cross bar folding, enables two side stands close to each other.A cross bar can also be used only in bottom bar 15, use
Two can make vehicle frame more firm, and intensity is higher.Locking releasing mechanism is provided in the middle part of cross bar 21, pressing the button that returns the vehicle to the garage and knock off can make
Above-mentioned four-bar mechanism unlock folds.The specific structure of locking releasing mechanism can be with reference to hand push disclosed in CN101909967A
Frame.
The bottom end of two cross foot levers 19 and the top that front-wheel makees bar 151 are hinged, and top and back link 14 are hinged.Two ten
The both ends interlocking bar 17 hinged with both respectively is provided between the bottom of word crossbar 19 and the respective end of cross bar, if
Setting when interlocking bar 17 collapses cross foot lever 19 drives cross bar 22 to fold, and returns the vehicle to the garage and knock off more smoothly.In order to allow 22 folding of cross bar
It drives cross bar 23 also to fold when folded, drive rod 24 is provided between cross bar 22 and cross bar 23.The both ends of drive rod respectively with cross bar
22 and cross bar 23 corresponding two ends it is hinged.Cross bar is reverse folded in order to prevent, the cradle head of cross bar 22 and cross bar 23
Place is provided with unidirectional position-limit mechanism.
The top of handspike 11 is set there are two handle 12, the plane where two vertical handspikes 11 of handle 12.Handspike
Sunshade mounting base 3 is also arranged on 11, inner concave arc surface is arranged in the medial surface of sunshade mounting base, as shown in figure 4, sunshade is pacified
The inner concave arc surface of dress seat 3 blocks front rod 13, avoids vehicle frame Automatic-expanding.
A bar 18 is additionally provided on each side stand 1, seat bar 19 and front rod 13 are rotated hingedly, be provided on back link 14
The sliding sleeve 181 being slidably matched with seat bar 18, when vehicle frame folding, seat bar is rotated around rotating joint, and sliding in sliding sleeve 181
It is dynamic, finally substantially remained on same straight line with front rod 13, back link 14.
Utility model works principle is as follows：
When returning the vehicle to the garage and knock off, operator's one hand presses the button that returns the vehicle to the garage and knock off on cross bar 21, is folded down cross bar 21, while four-bar mechanism solution
Lock folds, and front rod 13 is rotated around with the hinge joint of front-wheel seat bar 11, close to bottom bar 15, back link 14 around with bottom
The hinge joint of bar 15 rotates, close to bottom bar 15, and handspike 11 is rotated around with the hinge joint of front rod 11, and front link 11 leans on
Closely.
Because cross bar 21 folds, drive two handspikes 11 opposite close, so that two right-angled intersection bars 19
Collapse, right-angled intersection bar 19 drives cross bar 22 and cross bar 23 to fold by interlocking bar 17, the body frame structure for automotive finally folded such as Fig. 3 and
Shown in Fig. 4.
In order to enable the length of front rod 13 more compact and the length of bottom bar 15 are of substantially equal after vehicle frame folding, handspike
Top be substantially flush with front-wheel, bottom end is substantially flush with rear-wheel substantially, and the inside of handle 12 is close to the wheel edge of front-wheel.
